Salah satu upaya dalam pemanfaatan tanah berpasir adalah dengan menambahkan bahan amelioran. penambahan bahan amelioran dapat menggunakan kompos yang berperan penting dalam meningkatkan sifat fisik, kimia dan biologi tanah. Tujuan dari penelitian ini untuk mengetahui pengaruh kompos dan arang aktif sebagai bahan amelioran pada tanah berpasir terhadap pertumbuhan tanaman sawi (Bressica juncea L). Penelitian dilaksanakan di Rumah Kaca STIPER Dharma Wacana Metro, sedangkan analisis tanah dilakukan di laboratorium Balai Penelitian Tanah Taman Bogo Lampung. Rancangan penelitian menggunakan rancangan acak kelompok (RAK) dengan 4 perlakuan dan 3 ulangan. Parameter yang diamati pada tanaman adalah berat basah dan berat kering tanaman dilakukan pada akhir setelah panen dipanen. Sedangkan parameter sifat tanah yaitu pH, kadar air, N-Total, dan C-organik. Hasil penelitian menunjukkan penggunaan bahan amelioran dalam bentuk arang aktif dan kompos dapat memperbaiki sifat tanah berpasir yang ditunjukkan dengan peningkatan pH, kadar air, C-organik, dan N-total. Pengaruh pertumbuhan tertinggi ditunjukkan pada perlakuan PK yaitu 9.86 gram. Sedangkan pada pertumbuhan akar tanaman tertinggi ditunjukkan pada perlakuan PKA sebesar 1.07 gram. Secara umum penggunaan amelioran pada penelitian ini memberikan pengaruh yang baik terhadap perubahan sifat tanah berpasir dan pertumbuhan pada tanaman caisim.

Kimchi is a food that has a distinctive taste, which is sour due to the fermentation process. Kimchi made from vegetables and various spices in the form of spices. This research is about salt concentration and fermentation time on vitamin C content and organoleptic quality of kimchi pakcoy. The research method used is the method of description (single factor; two replications) by presenting the results of observations in the form of a histogram, then discussed descriptively. The treatment factor is a combination of salt concentration and fermentation time. Salt concentration (K) which consists of 3 levels, namely: K1 (2%), K2 (4%) and K3 (6%) and the duration of fermentation (L) which consists of 3 levels, namely: L1 (2 days), L2 (4 days) and L3 (6 days). The parameters analyzed were vitamin C content and organoleptic quality related to taste, aroma, color and texture. Salt concentration and fermentation time greatly affect the content of vitamin C and organoleptic quality. The highest vitamin C content was found in the K3L3 sample, namely 6% salt concentration and 6 days of fermentation time with a vitamin C content of 0.7320 mg / gr. Organoleptic quality using the hedonic test, related to taste, aroma, color and texture, yielded successive values, namely 5.2 (K3L2); 5,6 (K2L3); 5.9 (K1L1); 6.1 (K1L1)

One of the efforts in sandy soil utilization is to add ameliorant material. The addition of ameliorant material can use compost that plays an important role in improving the physical, chemical and biological properties of the soil. The purpose of this study was to determine the effect of compost and activated charcoal as ameliorant material on sandy soil to the growth of mustard plant (Bressica juncea L). The study was conducted at Greenhouse of STIPER Dharma Wacana Metro, while soil analysis was conducted in Taman Bogo Soil Research Laboratory. The results showed that the use of ameliorant material in the form of activated charcoal and compost can improve the sandy soil properties as indicated by the increase of pH, moisture content, C-organic, and N-total. The highest effect of growth was shown in the treatment of PK that is 9.86 gram. While, the highest growth of plant roots is shown in 1.07 gram of PKA treatment. In general, the use of ameliorants in this study has a good effect in the change of sandy soil properties and growth in mustard plants.

Mungbean are one of the food crops that produce 22% vegetable protein sources. It’s the third food crop after soybean and peanut. It has the potential to be developed because high economic value. The price is quite stable when compared to other food commodities. Cow manure can increase the nutrient content, the physical and chemical properties of the soil. You can also provide liquid organic fertilizer in the form of KSM to add the nutrients. KSM fertilizer is a new fertilizer circulating at the farmer level. It’s claimed to increase the absorption of fertilizer by plants. Research method used was a completely randomized block design which arranged in a factorial manner with three replications. The first factor is the dose of manure and the second factor is the frequency of fertilization of KSM to promote plant growth. Treatment without manure and KSM is as a comparison factor (control). The results showed that the dose of 1.2 kg of manure and the time of spraying every 3 days after planting could increase the growth and yield of mungbean. Dosage of manure and time of spraying don’t interact both of them.

Liquid organic fetilizer (POC) is a fertiizer that is applied to leave. The advantage of providing fertilizer through the leaves in a way that is more easily absorbed by plants, both macro, and micronutrient. The objectives of this research were conducted to: (1) Fertilization time interval on the growth and yield of red spinach plants. (2) Effect POC concentration on growth and yield of red spinach tanaman. (3) Interaction between fertilization interval and effect POC concentration on growth and yield of red spinach.This research was carried out at the Experimental Garden of STIPER Dharma Wacana Metro in November – December 2019. This study uses a Randomized Complete Block Design (RCBD) and was arranged in a factorial consisting of 2 factors in 3 replications. The first factor is the time of fertilization (w) which consists of 3 levels, (w1=once every 3 days, w2=once every 5 days, w3= once every 7 days). The second factor is the provision of liquid organic fertilizer (k) which consists of 3 level (k1= 5 cc/L water, k2=10 cc/L water, k3=15 cc/L water. The data obtained were tested for analysis of variance follwed with the least significant difference test (LSD) at the 5% level. The results showed that the time of fertilization was significant to the planting weight. Fertilizing time interval every 3 days gave better results, namely 18.94 g. There was no interaction between time interval and concentration of POC fertilization on growth and yield red spinach for all variables.

Sunflower seeds are the second largest producer of vegetable oil in the world. Sunflower seeds production ranks third in the world after peanuts and soybeans. Efforts to increase sunflower growth are through cultivation techniques including fertilization with the right dosage and treatment in the form of defoliation. Defoliation aims to increase the intensity of sunlight that can be received by plants, so that it will increase crop yields. Decreasing the intensity of sunlight can reduce yields by 40%. This research was conducted using the experimental method which was arranged in a factorial manner in a Completely Randomized Block Design. The first factor was the Professional NPK dose which consisted of two levels including the recommended dose (P1) and half the suggested dose (P2). The second factor is defoliation time which consists of three levels including phase R1, phase R2, and phase R3. The number of leaves removed is 30% of the number of leaves. The results showed that (1) the half recommended dose of NPK Professional in phase R3 had an effect on the variables of plant height and number of leaves and the recommended dose of Professional NPK had an effect on stem fresh weight; (2) The recommended dose of Professional NPK effects the variables of stem diameter and flower diameter in R2 phase, the recommended dose of Professional NPK affects root dry weight in R2 phase, and the weight of 100 seeds in R1 phase. (3) There is an interaction between the dosage of NPK Professional and defoliation time of sunflower plants. Keywords : Sunflower, NPK, Defoliation
